In an ideal system the VSWR would be 1 and the loss would be 0dB, in reality that will never happen but we try to get the best performance we can from the components we use. In fiber-optic networks like FTTx and PON, PLC splitters are key components for distributing optical signals to multiple users. However, each splitter has complex parameters, including insertion loss, return loss, polarization-dependent loss, and uniformity. The. It is a measure of how much signal power is reflected by the switch back to the source where the signal is absorbed and is a primary signal that the VNA measures. Industry practice is to show this as the input Voltage Standing Wave Ratio (VSWR) and the VNA conveniently converts its measurements to. To maintain optimum signal integrity and power transfer, remember to terminate all unused ports with a well-matched 50 ohm coaxial load! See SMA Male Termination PD5182 is a DC blocking, eight way, RF broadband, 50 ohm, power divider, power combiner furnished with SMA coaxial connectors. Below, we take three representative models as engineering cases— a 350–2700 MHz 50W Wilkinson splitter, a 698–7125 MHz cavity.
